Lower concern. Standard insole materials rarely treated with PFAS.
PowerStep Pinnacle insoles use common foam and fabric with no known PFAS-treatment standard in orthopedic footwear. No lab data or brand disclosure available, but category risk is modest.

The full breakdown
What it's made of and why it matters
PowerStep Pinnacle High Insoles use EVA (ethylene-vinyl acetate) foam as the primary cushioning material, paired with fabric coverings and possibly polyurethane or rubber components. EVA is a closed-cell foam widely used in footwear because it resists moisture, compresses predictably, and does not leach into skin under normal wear. The fabric layer is the main contact surface; its composition (polyester, nylon, or cotton blend) determines off-gassing and dye-related risks.
The brand's record and disclosure
Pinnacle does not publish detailed material safety data, ingredient lists, or chemical certifications on the insole product. The company has no known safety recalls or regulatory actions tied to these insoles. Without independent testing or third-party certifications (such as OEKO-TEX or similar textile standards), consumer transparency is limited to material type claims.
How it compares in its category
EVA foam insoles are industry standard and carry lower chemical risk than gel or memory-foam alternatives, which can off-gas volatile compounds during manufacture and early use. Most retail insole brands (Superfeet, Dr. Scholl's, Spenco) use similar EVA or polyurethane bases. PowerStep's lack of published certification is typical for the market; premium brands often add third-party testing, but absence does not indicate failure.
If you buy it
Store insoles in a cool, dry place away from direct heat or sunlight, which can accelerate foam degradation. Expect a lifespan of 6-12 months with regular daily wear before cushioning noticeably flattens. Hand-wash the fabric cover periodically with mild soap and water; avoid machine washing or bleach. Replace when cushioning becomes firm or uneven, or if odor persists after cleaning.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Formaldehyde in textile coatings or dyes
Fabric-covered insoles may use formaldehyde-based resins in finishing or dye fixation, but this is not documented for Pinnacle Pinnacle High. Standard textile safety applies; direct skin contact is minimal inside footwear.
Azo dyes in fabric layer
If the fabric covering uses synthetic dyes, azo colorants are common in low-cost insoles and pose minimal risk via skin contact during short daily wear. No specific testing published for this product.
EVA foam degradation and microparticle shedding
Over extended use, EVA foam can shed microscopic particles inside shoes; this is mechanical wear rather than chemical leaching and is not unique to Pinnacle. Rate depends on foot friction and insole age.
Antimony in polyester or synthetic materials
Antimony trioxide is sometimes used as a catalyst in polyester production but is not typically released during normal wear of finished insoles. Pinnacle does not disclose polyester source or processing.
VOC off-gassing from new foam or adhesives
New EVA insoles may emit weak odors (volatile organic compounds) for the first few days to weeks; this is common in the category and typically dissipates with ventilation. No specific data for Pinnacle brand.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 72% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
